The Vortex Shedder\u00ae incorporates an aerodynamic geometry to reduce the leakage flow while improving stage heat rate performance. Whether the steam path design is impulse, reaction, or a combination of both, the vortex can have a significant improvement on stage efficiency above the original design.<\/p>\n<p>Our stainless Vortex Shedder\u00ae Tip Seals work by creating vortices at the admission side of the seal. These vortices reduce the pressure drop, resulting in lower flow and less leakage across the seal. This translates to improved stage heat rate performance for the steam turbine.\u00a0PATENT NUMBER: 5,735,667<\/p>\n<ul>\n<li>The Vortex Shedder is a shape applied to a seal, creating small vortices at the seal tooth.<\/li>\n<li>These vortices create a pressure barrier at the tooth, lowering the change in pressure (\u0394P) across it.<\/li>\n<li>Lowering the \u0394P seal increases efficiency.<\/li>\n<li>Lower \u0394P also means less flow, resulting in longer seal life at the higher efficiencies.<\/li>\n<li>When combined as an integrated sealing system, Guardian packing rings &amp; Vortex Shedder tip seals are proven to increase overall turbine efficiency above design by 1.5% &#8211; 4.5%.<\/li>\n<li>Increased unit efficiency translates to lower EPA emissions per megawatt\/hr, as well as, lower operating costs.<\/li>\n<\/ul>\n<p><b>Simple and Effective:<\/b><\/p>\n<ul>\n<li>No Stationary Fit Modifications<\/li>\n<li>Uses Design Radial Clearances<\/li>\n<li>Made From Stainless Steel Material<\/li>\n<li>Reduces Leakage Flow in CFD Modeling by 5.7% Compared to Conventional Seal<\/li>\n<li>Lower Flow Delivers Higher Efficiency &amp; Less Wear<\/li>\n<\/ul>\n<p>Learn more about the other\u00a0<a href=\"https:\/\/www.mdaturbines.com\/resources\/steam-turbine-parts-solutions\/\">Steam Turbine Parts<\/a>\u00a0that MD&amp;A offers.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>MD&amp;A Parts Division offers the patented advanced design Vortex Shedder\u00ae\u00a0spill strip.
